You betcha. All of them look fairly interesting too. It's kind of similar to how Sunrise built up all those extra side story entries around Code Geass with the Picture Drama and Mangas. One is a prequel, one's a straight up adaptation, and one is running concurrent with the events of the show.

I hope Bandai/Sunrise keeps up with the practice. It's kind of similar to how a lot of popular American TV thrillers are adding material on the side to enhance viewer interest, if not quite as direct an approach. They did it with Xenoglossia too by having Haruka Amami maintain a blog that ran concurrent to the show. Anyways I digress, to date I don't think any announcements have been made about scanlating them, but I hope to be one of the first to learn of any such project.
